Feed Stretching DNA To The Limit (sciencedaily.com)

From feed by sdfeed
A group of researchers at Duke University have developed a method to measure changes in the mechanical properties of DNA upon irradiation with UV light. This work might pave the way for using stretch-release force spectroscopy measurements in DNA diagnostics.

Feed Towards Rational Vaccine Design (sciencedaily.com)

From feed by sdfeed
The immune system recognizes vaccine agents as foreign, destroys them, and "remembers" them. When the virulent version of an agent comes along, the immune system is thus prepared to respond. This long term immunity relies heavily upon the generation of so called B cells, which will generate antibodies that will bind to pathogens and mark them for destruction. A recent study describes strategies for vaccine design, specifically selective priming of B cells using various adjuvants.

Submission + - Net Neutrality, take 2: Jeffersonet vs. Edisonet

Submitted by

PetManimal writes: "Curt Monash has an interesting take on the 'Net neutrality debate. His middle way notes that the classic "Jeffersonet" — which includes e-mail, instant messaging, much e-commerce, and most websites created in the first 13 or so years of the Web — is "the greatest tool in human history to communicate research, teaching, news, and political ideas, or to let tiny businesses compete worldwide", and cannot be compromised by a tiered Internet. On the other hand, he continues, a reliable, tiered scheme is required for what he calls the "Edisonet" — which consists of "communication-rich applications such as entertainment, gaming, telephony, telemedicine, teleteaching, or telemeetings of all kinds." Richi Jennings points to a lack of investment in Internet infrastructure and IPv6 technologies that's the root of the problem:

Of course, if an application writer makes assumptions that ignore realities such as the speed of light or temporary congestion, their application's going to behave badly. But no premium QoS in the world is going to help that. My sense is still that the ISPs that are complaining about net neutrality are simply being greedy and don't want to invest money to cope with the growth in usage.
